- Refactored `Jido.Agent.__using__/1` macro by extracting quoted code into
  separate helper functions to avoid Credo "long quote blocks" and "nested
  too deep" warnings. Compile-time validation and runtime code are now
  clearly separated.

- Applied similar decomposition to `Jido.Skill.__using__/1` macro, breaking
  it into focused helper functions for behaviour setup, accessors, and
  callbacks.

- Extracted complex conditional logic into private helper functions across
  multiple modules (AgentServer, Cron directive, Await, Routes, etc.) to
  improve readability and reduce nesting depth.

- Standardized alias usage throughout codebase: added module aliases at top
  of files and replaced inline module references with aliased versions.

- Fixed idle timer handling in Keyed lifecycle to use `:erlang.start_timer/3`
  with timer refs instead of `Process.send_after/3`, preventing stale timeout
  messages from triggering after cancel/reset.

- Added `restart: :transient` to InstanceManager child specs to avoid
  immediate restarts on normal shutdown/idle timeout while still allowing
  restarts on crashes.

- Added logger configuration for Jido telemetry metadata keys.

- Replaced `length(list) >= N` comparisons with pattern matching or `!= []`
  in tests for more idiomatic Elixir.

- Used `Enum.map_join/3` instead of `Enum.map/2 |> Enum.join/2` where
  applicable.

- Reordered aliases alphabetically in test files for consistency.
